It should be understood that the detailed description is presented herein only to illustrate the present disclosure and not to limit the scope of the disclosure.

Electronic devices such as mobile phones and tablet computers are indispensable scientific and technological products in the life, study and entertainment processes of people, and bring convenience and fun to the life of people. Along with the development of diversification of electronic equipment functions, electronic equipment is various in variety and brands are various, so that consumers can select a plurality of electronic equipment, the requirements of people on the electronic equipment cannot be met only by improving the functional characteristics of the electronic equipment, and the aesthetic property of the shell structure of the electronic equipment is also an important factor for influencing the competitiveness of electronic products. Among electronic devices having similar functions or performances, the more beautiful the appearance of the electronic device is, the more attractive consumers can be attracted to purchase.

While flexible display screens are becoming more and more popular for use on electronic devices. The foldable electronic equipment using the flexible display screen can be folded in half so as to be convenient to carry; the flexible display screen has a larger display area after being unfolded, and is further favored by consumers.

In the related art, however, a mechanical folding mechanism is required to fold the flexible display screen, so that the flexible display screen is ensured not to have faults in the normal use process and not to be affected by normal bending of the flexible display screen; and the folding mechanism cannot damage the flexible display screen. However, the conventional folding mechanism has poor hovering effect, which is not beneficial to improving user experience.

Based on the above, the present disclosure provides a rotating component, which has a good hovering effect, can realize hovering and folding of a folding mechanism, and is beneficial to improving user experience of foldable electronic equipment.

For a better understanding of the rotary member of the present disclosure and the folding mechanism to which the rotary member is applied, explanation is made by a foldable electronic device to which the folding mechanism is applied.

As shown in fig. 1 and 2, in some embodiments of the present disclosure, a foldable electronic device 10 is provided that includes a flexible display screen 11 and a folding mechanism 12. The folding mechanism 12 can drive the flexible display screen 11 to switch between an unfolded state and a folded state, and support the flexible display screen 11 when the flexible display screen 11 is in the unfolded state.

As shown in fig. 2, wherein the folding mechanism 12 includes a base assembly 100, a support 200, and a rotating member 300. The rotating member 300 includes a mounting assembly 310, a rotating assembly 320, a friction assembly 330, and an elastic assembly 340. The mounting assembly 310 includes a first fixing member 311, a second fixing member 312, and a mounting rod 313 disposed between the first fixing member 311 and the second fixing member 312, wherein the mounting rod 313 is disposed between the first fixing member 311 and the second fixing member 312. The rotating assembly 320 includes a rotating member 321, and the rotating member 321 is rotatably coupled to the mounting assembly 310 through a mounting rod 313. The friction assembly 330 includes at least one friction member 331, and the at least one friction member 331 is rotationally connected to the rotating member 321 in synchronization with the rotating member 321 and is disposed between the rotating member 321 and at least one of the first fixing member 311 and the second fixing member 312. The elastic member 340 is disposed on the mounting member 310 to press the at least one friction member 331. The mounting assembly 310 is disposed on the base assembly 100, and the support member 200 is rotatably coupled to the rotating member 321 and the base assembly 100, respectively.

Thus, when the rotating member 300 is applied to the folding mechanism 12, in the process of rotating the rotating member 321, the friction member 331 rotates synchronously with the rotating member 321, and the friction member 331 is pressed on the mounting assembly 310 by the elastic assembly 340, so that the rotation damping of the rotating member 321 can be increased, the rotating member 321 can be fixed on the mounting assembly 310 when not driven by the rotation force, and the hovering effect of the folding mechanism 12 is improved.

When the foldable electronic device 10 is used, the rotating assemblies 320 at two sides of the base assembly 100 rotate around the base assembly 100, and the rotating member 321 can drive the supporting member 200 to rotate, so that the supporting member 200 is switched between the supporting state and the avoiding state, and the flexible display screen 11 is switched between the unfolded state and the folded state. In the process of rotating the rotating member 321, the friction member 331 rotates synchronously with the rotating member 321, and the friction member 331 and the elastic component 340 are pressed on the mounting component 310, so that the rotation damping of the rotating member 321 can be increased. In this manner, the rotational member 321, when not driven by a rotational force, may effect the securing of the support member 200 to the base assembly 100 to effect hovering. In this way, the foldable electronic device 10 utilizes the rotating component 300 to fix the flexible display screen 11 at least in the unfolded state, so as to be convenient for people to use; and at least can be fixed in a folded state so as to be convenient for people to carry.

In other embodiments, the foldable electronic device 10 utilizes the rotating member 300 to allow the flexible display screen 11 to hover in any position, either folded or unfolded.

It will be appreciated that the resilient assembly 340 cooperates with the friction member 331 to provide a hover effect for the rotational member 321, which is simple to operate, and the magnitude of the friction force can be easily adjusted to meet the desired hover effect.

It should be noted that "hovering" is understood to mean that the rotating member 321 can be kept at a certain position when not being driven, so that a certain rotational force is applied to the rotating member 321, so that the rotating member 321 can rotate, and when the rotational force is cancelled or reduced, the rotating member 321 can be fixed at a certain position without rotating.

It should be noted that, the specific implementation manner of the friction element 331 disposed between the rotating element 321 and at least one of the first fixing element 311 and the second fixing element 312 may be various, including, but not limited to, that the friction element 331 is directly or indirectly sandwiched between the rotating element 321 and the first fixing element 311; alternatively, the friction member 331 is directly or indirectly sandwiched between the rotating member 321 and the second fixing member 312; alternatively, the at least one friction member 331 is directly or indirectly sandwiched between the rotating member 321 and the first fixing member 311, and the at least one friction member 331 is directly or indirectly sandwiched between the rotating member 321 and the second fixing member 312, and so on. The friction member 331 can damp the rotation of the rotator 321.

When the flexible display 11 is in the unfolded state, the supporting member 200 is in the supporting state, so as to support the effective display. And when the flexible display screen 11 is in a folded state, the supporting piece 200 is in an avoidance state, so that an avoidance space for avoiding bending of the flexible display screen 11 can be formed, and the flexible display screen 11 is folded in half reliably.

In some embodiments, as shown in fig. 2, the number of the rotating members 321 and the supporting members 200 is at least two, and the rotating members and the supporting members are respectively disposed on two sides of the base assembly 100 in a one-to-one correspondence manner, and at least part of the flexible display screen 11 is disposed to cover the two supporting members 200. In this way, the folding of the flexible display screen 11 in a laminated state or the opposite unfolding in a plane is facilitated.

It will be appreciated that the rotating member 300 is modularly installed in the folding mechanism 12 by the mounting assembly 310, combining the rotating assembly 320, the friction assembly 330 and the elastic assembly 340 into a single module, and then securing the rotating assembly with the base assembly 100 by the first securing member 311 and the second securing member 312.

It should be noted that the first fixing member 311 and the second fixing member 312 may be fixed to the base assembly 100 in various manners, including but not limited to screw fixing, snap fixing, riveting fixing, welding fixing, etc.

Furthermore, in other embodiments of the folding mechanism 12, the "mounting assembly 310 and the base assembly 100" may be assembled first and used as a stand module in the folding mechanism 12 to effect the mounting of the friction member 331, the rotational member 321, the elastic assembly 340, and the support member 200.

Based on any of the above embodiments, as shown in fig. 2 to 4, in some embodiments, the base assembly 100 includes a base 110 and a guide 120 rotatably disposed on the base 110, the support 200 includes support members 200 corresponding to the rotating members 321 one by one, and the support members 200 are rotatably connected to the guide 120 and the rotating members 321, respectively, so as to have a supporting state and an avoidance state.

As shown in fig. 2 to 5, further, in some embodiments, one of the supporting members 200 and the guiding member 120 is provided with a first arc-shaped guiding portion 121, the other is provided with a first guiding body 210 slidably engaged with the first arc-shaped guiding portion 121, one of the supporting members 200 and the rotating member 321 is provided with a second arc-shaped guiding portion 220, and the other is provided with a second arc-shaped body slidably engaged with the second arc-shaped guiding portion 220. In this way, it is facilitated to realize that the supporting member 200 is on the same plane in the supporting state for supporting the flexible display screen 11 in the unfolded state. In the retracted state, the supporting member 200 may form a water drop-shaped retracted space, so as to reduce stress applied to the flexible display 11 in the folded state.

It should be noted that, the guide 120 cooperates with the rotating member 321, and various manners of implementing the switching between the supporting state and the avoiding state of the supporting member 200 may be provided.

It should be noted that the "guide 120" may be one of the parts of the module "the base assembly 100", that is, assembled with the other components "of the base assembly 100 to form a module, and then assembled in a modularized manner; or may be separate from the other components of the base assembly 100, and may be separately mounted, i.e., integral with the other components of the base assembly 100 in the present apparatus.

It should be noted that, the "rotating member 321" may be one of the parts of the module "rotating member 300", that is, may be assembled with other components "of the rotating member 300 to form a module, and then be assembled in a modularized manner; may be independent of the other components of the rotating member 300, and may be separately mounted, i.e., may be integrally formed with the other components of the rotating member 300 in the present apparatus.

Equivalently, the components contained in the components, parts, mechanisms and equipment of the disclosure can be flexibly combined, i.e. can be modularly produced according to the actual situation, and can be modularly assembled as an independent module; or may be assembled separately to form a module in the device. The above-mentioned components are divided into only one embodiment of the present disclosure, and for convenience of reading, not limitation of the scope of protection of the present disclosure, so long as the above components are included and the same function should be understood as the equivalent technical solutions of the present disclosure.

The rotary member 300 is further described below with reference to fig. 2 and 5-12.

It should be noted that, the friction member 331 and the rotating member 321 may be synchronously and rotatably connected in various manners, including but not limited to, the friction member 331 is directly or indirectly in driving connection with the rotating member 321; alternatively, the friction member 331 is directly or indirectly in driving connection with the mounting bar 313, and synchronously drives the rotation member 321 to rotate by using the mounting bar 313; alternatively, the friction member 331 is connected to other transmission components such that the friction member 331 rotates in synchronization with the rotating member 321.

On the basis of any of the above embodiments, as shown in fig. 2 and fig. 5 to 7, in some embodiments, the friction member 331 is rotatably connected to the mounting assembly 310 through the mounting rod 313, and the rotating member 321 is in driving connection with the friction member 331. In this way, the friction piece 331 is installed on the installation component 310, and the rotation piece 321 is in transmission connection, so that the friction piece 331 is driven to rotate through the rotation piece 321, synchronous rotation of the friction piece 331 and the rotation piece is achieved, and rotation damping of the rotation piece 321 is increased by the aid of the friction piece 331. The friction member 331 is rotatably connected to the mounting assembly 310 through the mounting rod 313, so that the structure of the rotating member 300 is more compact, which is beneficial to the miniaturization development of the foldable device.

It should be noted that the specific implementation of the driving connection between the rotating member 321 and the friction member 331 may be various, including, but not limited to, a non-detachable fixed driving connection and a detachable fixed driving connection, for example, screwing, riveting, welding, detachable sleeving, and a synchronous shaft connection.

Further, as shown in fig. 2 and fig. 5 to 7, in some embodiments, the rotating member 321 is provided with a driving arm 3211, and the friction member 331 is provided with a swing arm 3311 fixedly connected to the driving arm 3211. In this way, through the fixed connection of the driving arm 3211 and the swing arm 3311, the synchronous rotation of the rotating member 321 and the friction member 331 is realized, so that the positions of the rotating member 321 and the friction member 331 can be flexibly set, and other components are convenient to integrate to promote the hovering effect of the rotating member 321.

It should be noted that the fixing manner of the driving arm 3211 and the swing arm 3311 may be various, including but not limited to screwing, riveting, welding, clamping, etc.

In combination with the above embodiments of the driving arm 3211, as shown in fig. 5 and 7, in some embodiments, a clamping hole 3201 is provided between one driving arm 3211 and the swing arm 3311, and a clamping protrusion 3301 is provided between the other driving arm 3211 and the clamping hole 3201.

Alternatively, the mounting rod 313 is rotatably disposed between the first fixing member 311 and the second fixing member 312, and the rotating member 321 and the friction member 331 are connected to the mounting rod 313, respectively. In this way, the state of the mounting rod 313 can be combined, the rotating member 321 and the friction member 331 can rotate relative to the first fixing member 311 and the second fixing member 312, so that the synchronous rotation of the rotating member 321 and the friction member 331 can be realized by using the mounting rod 313, the structure of the rotating member 300 is more compact, the modularized assembly is easy, and the assembly efficiency of the foldable electronic device 10 is improved.

In this way, the damping member 350 can further increase the rotation damping of the rotating member 321, thereby improving the user experience of the foldable electronic device 10. In particular, in the unfolded state and the folded state, the damping member 350 is utilized to increase the rotation damping of the rotating member 321, so that the flexible display screen 11 can be fixed in the unfolded state for the convenience of the user. The flexible display screen 11 can also be fixed in a folded state, so that the flexible display screen is convenient for a user to carry and cannot be unfolded easily.

When the rotator 321 is in the first state, the first protrusion 3213 is disposed in the second groove 351, and the second protrusion 352 is disposed in the first groove 3212. When the rotator 321 is in the second state, the second protrusion 352 abuts against the first protrusion 3213 to press the elastic component 340. In this way, the rotating member 321 is in the first state corresponding to the rotation process of switching between the unfolded state and the folded state of the flexible display screen 11, the first protrusion 3213 is disposed in the second groove 351, the second protrusion 352 is disposed in the first groove 3212, and the damping member 350 does not generate damping to the rotating member 321 or generates small damping, so that the folding mechanism 12 is convenient to rotate, so as to drive the flexible display screen 11 to move. At this time, the friction member 331 is used to achieve a hover effect of turning and stopping. The rotating member 321 is in the second state corresponding to the flexible display screen 11 in the unfolded state or the folded state, and the second protrusion 352 abuts against the first protrusion 3213 to squeeze the elastic component 340, so that the acting force of the elastic component 340 for squeezing the friction member 331 can be increased, and the rotation damping of the rotating member 321 can be increased, so that the rotating member 321 needs to overcome the larger rotation damping to perform the movement, that is, the rotating member 321 needs a larger driving force to rotate, so that the flexible display screen 11 can be fixed in the unfolded state or the folded state.

As can be appreciated, the friction member 331 rotates in synchronization with the rotating member 321, and a hovering effect of the rotating member 321 is achieved by the friction member 331 generating friction resistance. If the friction coefficient of the friction member 331 is large, abrasion is liable to occur, and after abrasion, the friction resistance generated by the friction member 331 becomes small, which is disadvantageous in providing a hovering effect for the foldable electronic device 10 for a long time. As shown in fig. 6, in any of the embodiments of the damping member 350, in some embodiments, an oil storage recess 302 is provided on a mating surface between at least one of the friction member 331 and the damping member 350. In this way, the friction member 331 is lubricated by storing the lubricating oil in the oil storage recess 302, the friction coefficient of the friction member 331 is reduced, the wear resistance of the friction member 331 is improved, and thus the hovering effect can be provided for the foldable electronic device 10 for a long time.

At this time, the frictional force generated by the friction member 331 is mainly adjusted by the pressing force of the elastic member 340.

Similarly, when the friction piece is clamped between the first fixed piece and the rotating piece, at least one of the first fixed piece and the rotating piece is provided with a second friction surface matched with the first friction surface, and at least one of the first friction surface and the second friction surface is provided with an oil storage concave part; and/or when the friction piece is clamped between the second fixed piece and the rotating piece, a third friction surface on the friction piece, at least one of the second fixed piece and the rotating piece is provided with a fourth friction surface matched with the third friction surface, and at least one of the third friction surface and the fourth friction surface is provided with an oil storage concave part. Therefore, the friction piece is lubricated by storing lubricating oil by the oil storage concave part, the friction coefficient of the friction piece is reduced, the wear resistance of the friction piece is improved, and a hovering effect can be provided for the foldable electronic equipment for a long time.
